Low Friction Tapered Roller Bearing 33210 For Industrial Equipment

Product Description of Tapered Roller Bearing 33210

I. Product Type and Core Positioning

33210 is a single-row tapered roller bearing, designed specifically to withstand combined radial and axial loads. It is suitable for heavy-load, high-speed conditions, featuring low friction, long service life, and easy maintenance, and is widely used in industrial equipment and automotive transmission systems.

II. Structural Design and Advantages

• Separable structure:
  The inner ring (including tapered rollers and cage) and outer ring can be independently installed/removed, facilitating equipment assembly and maintenance. Components are interchangeable, reducing operation and maintenance costs.
• Tapered raceway design:
  The raceways of the inner and outer rings, as well as the rollers, are tapered. The projection lines of the raceways intersect at the bearing axis, enabling pure rolling motion, which significantly reduces operational friction and energy loss.
• Preload adaptability:
  Supports paired installation of multiple bearings in "back-to-back" or "face-to-face" configurations. Preloading enhances system rigidity, meeting the requirements of high-precision equipment (e.g., machine tool spindles, gearboxes).

III. Key Technical Parameters (Typical values, based on brands like SKF)

IV. Performance Features

• High load-carrying capacity: Withstands both radial and unidirectional axial forces, suitable for heavy-load equipment (e.g., metallurgical rolling mills, mining machinery).
• Low friction and long service life: Pure rolling design reduces wear; bearing steel is strengthened by heat treatment to enhance fatigue resistance.
• Precision and stability: High-precision manufacturing processes (e.g., SKF Explorer grade) ensure low vibration and low noise during high-speed operation.

V. Typical Application Scenarios

• Industrial field: Food and beverage processing equipment, plastic sheet machinery, vertical rubber machinery, dump trucks, hoists, etc.
• Automotive industry: Transmission systems (e.g., differentials, gearboxes), heavy-duty axles, etc.
• Heavy machinery: Metallurgical equipment, mining crushers, construction machinery (e.g., excavator slewing rings), etc.

VI. Notes

• Ensure coaxiality of inner and outer rings during installation to avoid uneven loading that accelerates wear.
• Strictly control clearance during paired installation; optimize rigidity through preloading.
• Select lubrication methods (grease/oil), clearance classes (e.g., C3/C4), or anti-corrosion coatings according to working conditions to adapt to special environments (e.g., high temperature, dusty conditions).
